Bigger Size

Generally, a higher carat weight signifies a larger diamond, two similar carat weight diamonds can appear different in size depending on their cut.

FAQ on Diamond Size Chart

What is a respectable diamond size?

The most sought-after diamond carat range falls between 1.0 and 1.9, yet there are distinct surges in demand for diamonds size ranges within the 0.70 – 0.79, 0.90 – 0.99, and 1.50 – 1.59 carat.

The distribution of diamond size varies significantly depending on geographic location and the characteristics of the local population. For instance, in the United States, the typical diamond size for an engagement ring stands at approximately 1 carat. In contrast, across the pond in the United Kingdom, the average dips to 0.6 carats, while in Europe, it further decreases to approximately 0.5 carats.

The Diamond Size of 3.00 Carat is undoubtedly impressive and stunning that is observed very rarely in people’s jewelry.

As far as engagement rings are concerned, the average total carat weight in the United States is 1.08 carats. There are noticeable peaks at 0.70 to 0.79 carats, 0.90 to 0.99 carats, and 1.50 to 1.59 carats, although the range of 1.0 to 1.9 carats is by far the most popular.

A larger carat and a larger diamond are not always the same thing. So, avoid spending your hard-earned money on the carat weight alone. Rather, focus on all the individual characteristics to make a sound decision. In the end, a large diamond with poor color and clarity will not have the same amount of sparkle as compared to a lower-carat, higher-quality diamond.

No, the most important of the 4 Cs of diamonds is generally the cut. However, carat is indeed one of the important factors that decide the diamond’s overall quality and value. Therefore, cut is considered the most critical, followed by color, clarity, and carat weight.

The price of a diamond can also varies when it comes to diamonds with similar carat weights, due to a number of factors such as:

  • Carat Weight

    With its carat weight, the price of a diamond increases exponentially. A 1.5-carat diamond, for example, can cost more than 1.5 times as much as a 1-carat diamond.

  • Size Category

    The price per carat increases with the weight. Taking the example of a two-carat diamond might cost $6,820 per carat, as opposed to a three-carat diamond, which might cost $13,681.

  • Appearance

    The diamond’s actual appearance may affect its price, including any visible imperfections, defects, blurs, or shades.

  • Other Factors

    In addition to the 4 Cs of diamond grading (color, clarity, cut, and carat), demand and supply also influence the price of diamonds.

The higher the number of carats, the larger the diamond will often be. The measuring criteria of diamonds are their weights and not sizes. However, the cut can also affect the appearance of a diamond.
